Application filed March 16, 1914. Serial No. 824,866.

To all whom it may concern:

Be it knownthat I, EMILE F. OAMUs, a citizen of the United States,residing at Detroit, in the county of WVayne, State of Michigan, haveinvented certain new and useful Improvements in Socket Ratchet.-l/Vrenches; and I do declare the following tobe a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

This invention relates to socket ratchet wrenches, and consists in theconstruction and arrangement of parts as hereinafter more fullyset forthand pointed out particularly in the claims.

The object of the invention is to provide a simple and efiicient socketwrench to be usedby hand in setting up or Withdrawing nuts on threadedbolts, in which the con struction is such as to enable an intermittentrotation of the nut in either direction through an oscillatory movementimparted to the handle of the wrench, in such manner to obviate thenecessity for withdrawing the socket head of the wrench from the nut, orthe shifting of the hand upon the handle of the wrench in effecting therotation of the nut in either direction.

A further object of the invention is the provision of means for quicklyeffecting an adjustment of the ratchet driving means whereby the drivingdirection of the wrench may be reversed at will by the operator so as todirect the rotation of the nut in either a right or left-hand directionwhile-in operation. V a Y .The above objects are attained by theemployment of the structure illustrated in the accompanying drawings, inwhich,

Figure 1 is a perspective view of the wrench as it would appear when setfor operating the socket head in the-right-hand direction. Fig. 2 is aplan view of the wrench adjusted for operation in rotating the nut inthe left-hand direction, a portion of the body and socket of the wrenchbeing broken away to show the internal arrangement of the parts. Fig. 3is a central longitudinal sectiontaken through the wrench when set tooperate in theright-hand position, as shown in Fig. 1. i i

Referring to the drawings by the characters of reference marked thereon,1 designates the driving stem of the wrench which is eXteriorly screwthreaded as at 2 at one end and terminates in a squared shank 3 adaptedto be received by a squared aper ture in the handle 4, upon which saidhandle is rigidly secured and held against withdrawal by means of ascrew 5 threadedinto the end of said stem and engaging a washer 6 incontact with the outer face of said handle. The inner end ofthe stem 2is provided with a series of ratchet teeth 7 formed longitudinally andcircumferentially therein, and extending into the body of said stem is ascrew threaded aperture into which one end of a screw threaded stem 8 isrigidly secured to form a reduced extension with the stem 1.

Mounted to slide freely upon the driving stem 1 is a'shell or sleeve 9,one end of which projects beyond the inner ratchet toothed end of saidstem and is provided with a series of ratchet teeth 10 therein, whichare disposed in reverse relation circumferentially of said stem withrespect to the teeth of the stem 1. The rear end of the sleeve 9 isadapted to abut against a knurled thumb nut .11 mounted on the screwthreads 2 of the stem 1. Extending through the wallof the sleeve. 9 nearthe rear end thereof is an L-shaped aperture 12' through which a pin 13passes that is rigidly secured at one end in the body of the I stem 1.Said pin together with the L-shaped aperture 12 limits the longitudinalmovement of the sleeve 9 and serves in the manner of a bayonet lock inconjunction with the nut 11 for confining said sleeve against movementupon the stem l when shifted and engaged with said nut and pin at eitherend of said L-shaped aperture.

Mounted to slide freely on the stem 8 and adapted to enter freely withinthe end of the sleeve 9 is a bushing 14, which is provided at its innerend with a the body a so is set to rotate the socket head in therightseries of ratchet teeth 15 adapted to register and mesh with theratchet teeth 7 of the stem 1; The outer end of the bushing ll issecured rigidly within a stem 16 of a socket wrench head 17. The end ofthe stem'16 of said head is"v provided with a series of ratchet teeth 18adapted to register and mesh with the ratchet teeth 10 of the sleeve 9..The outer end of the socket head 17 is provided with an aperture 19' ofsuitable shape and size to receive the nut to be turned. As a means ofholding the. socket head and its bushing 14. against withdrawal from thestemj8, and to yieldably hold the ratchet teeth thereon 1 in contactwith the ratchet teeth'ot the stem 1 and sleeve 9, a coiled spring 20 isinterposed between the outer end; of. the bushing 14 and a washer 21secured on the end of said stem by means of a lock nut 22 thereon,whereby the expansive force of the spring 20 exerts an outward tensionuponthe stem 8 and aninward tension' upon the bushing ltcarrying theratchet teeth thereon into yielding contact with the ratchet teethof'the stem 1, when i the sleeve9 is shifted to the position with thepin 13 in engagement with the foot portion ofthe L-shaped slot 12, asshown'ln Figs' 1 and 3'. In this position the wrench nut is then screwedagainst the end of the ment oflits ratchet, toothed end with the ratchetteeth of the socket head 17, by con-' tact With-the face of the knurlednut 11;

The bushing 14 of said head will be carriedagainst the tension of the spring 20 longitudinally upon the stem 8,causing the ratchet teeth 15 thereonto disengage from the teeth 7 of thestem 1, as said sleeve reaches the'limit of its end" movement by contactof the pin 13 with'the end: of the L-shaped aperture 12. sleeve willthen belocked extended against the tension of the spring 20, throughengagethus the right-hand ratchet teeth 7 and 15 will be held out'ofengagement and'the 1eft hand ratchet teeth l0 and 18,.of the sleeve andsocket head, respectively, will be held in yielding engagement under thetension of the spring 20, whereby an oscillating move- Said ment of thehandle 1 will a left-hand' rotary movementto the socket head '17 V of ithe wrenchiaslclearly shown in Fig. 2.
